f 7 claims. fici. eea-283) This invention relates to locks and particularly tolocks for'sliding car doors.

It is an object of this invention to provide locks for sliding doors capable -of absorbing slack cre- I ated by the movementof the doors in closing direction. Y 1 A further object is to provide locks for sliding doors embodying a hasp and a pin andcapable of absorbing slack created by the movement of the doors in closing direction and constructed to prevent undesirableupward movement -of the Din.

Other objects of the invention will become clear as the description thereof proceeds. Y

In the drawing forming part of thisspecificanon: A A

e. Fig. 1 is a fragmentary elevation showinga lock embodying the invention applied to a double door construction for railway house cars.

The instant invention is illustrated in laelock adapted for application to theA double doors of a railway house carv with whichV it has its greatest n Itis tobe understood, howeventhat the lock may also be utilized vin conjunction with single doors of railway cars. .e

the double'door application illustrated lthe lock embodies a hasp fastenerll riveted upon one of the horizontal corrugationsA I I'of the metallic panel I2 of the main door I3 ofthe double doorconstruction. The free end of the neck I4 of the -hasp fastener-extends through a vertical corrugation I5 formed in the panell2 adjacent to the forward edge thereof and with which the horizontal corrugations II merge. I'he'hasp fastener I0 is reinforced by means of a member. I6 disposed upon the inside of the horizontal corrugation upon which the hasp fastener is mountedl The hasp fastener reinforcement is secured to the horizontal corrugation by the rivetswhich secure the haspfastener to the corrugation, and extends into the vertical corrugation I5. Thefreeend of the neck of the hasp fastener proiectsthrough an opening in the hasp fastener reinforcement and is preferably welded to the reinforcement, as

more clearly illustrated in Fig. 2 of the drawings.

door. The front and rear wens I9 and 2n ef the haspare connected by the rlongitudinally spaced side walls 2| and 22 so as to form an apertureV for the receptionof a locking pin, as hereinafter eX- Y plained. The rear wall 20 of the hasp is provided with reinforcing ribs 23 and 24 which in the operative position of the lock are adapted to bear against a lock bracket 25 secured to the auxillary door 26 of the double `door construction;l

The` auxiliary door 26 comprises a metallic panel 21 whose'construction is substantially 'similarto that of the'metallic panel I2 of themain door.A I3 with the exception that certain of the horizontal corrugations'28 of the metallic panel 2l terminate agreater distance inwardly from the forward edge of the auxiliary'door panel than the horizontal corrugations I I formed in the metallic panel VI2 of the main door. This construc-V tion provides a at portion 29 in the auxiliary door panel 21 upon which the lock bracket 25 is secured so that the projection of the lock bracket outwardly from the auxiliary door is reduced. It Will be understood that the horizontal corrugations 28 and the front marginal construction oftheauxiliary door may be the same as that of the main door and that the lock bracket 25 will be correspondingly modiedrso as to it upon the corrugations where the projection of theelock bracket is not limited. e e 'A f The lock'brack'et 25, which is preferably in the form of a casting; is provided withl vertically spaced housing members 30 and 3i between which the hasp I1 is received when the lock is 'in Aits operative position so that the aperture formed bythe walls lil- 22, inclusive, of the hasp is alined with the openings provided by the housings 3i) and 3|. In the operative position of the haspA the rear wall 20 and the reinforcingribs 23 and 24 arefadapted to bear against theA lock bracket 25 which is reinforced byrmeans of an angle 32 disposed upon the inner face of the metallic panel 21 and secured theretoand to the lock bracket as by `means of rivets 33. The height of the reinforcing angle member 32 is preferably the'sarne as that of the lock bracket. The reinforcing' angle member32-is also Vsecured as"V by means of rivets-34 to a metallic post- 35 rigidly secured to and carried by the auxiliary doen-'as more clearly appears from Fig. 2 of the drawings. e

The lock bracket 25 is formed with a rib 36 which carries a projection, preferably in the formV of a rivet 31, for a reason which will hereinafter appear. At its lower portion the lockjbracketis fgrmed with a rib as prcvided with a. seal slot s of the pin is similar to that of the rear wall of the hasp l1 with which wall the pin cooperates,V

as hereinafter explained. The side faces 43 and M of the pin 40 are vertical. .'I'he .side .face 4310i the pin is formed with a shoulderfhi adaptedto engage the projection 3l so as to prevent lesstof the pin. The pin 4U is alsoformedwith an ear 46 having a seal slot 41 which is adapted to be A alined with the seal slot 39 so as to receivea riby bon seal.

'The lockfis shownin itsoperativeposition with the lmain and auxiliary doors fully'closed iniF-ig. l of the drawing. In this position-as Well as in all operative positions of the lock, the pin extends through the housings 3D and 3| and through the aperture formed in the hasp Il. `By reason of the instant invention :the `main Vand auxiliary doors Iof the double :door-construction. may be securedtogetherby the lockeven prior to thetime when the main Vand auxiliary doors 1are fully closed. vThe .relationship betweenthe locking piu, the hasp andthe lock bracket when the lock is in its operative position is amore clearly vshown zin Figs. 2 and 3 .of the drawing 4from which .it will be observed that the inclined portions .of 'the pin and 'the'wall 20 of the hasp arefin'engagement and the front face `.of the pin and the housing members 30 .and 3| -arein engagement. In the event that the doors are not :fully closed, it will be apparent that the :relationship lbetween the inclined portions .of the fpin Vand the .rear wall 20 of the hasp williprevent a movement of the main door in opening direction away from the .auxiliary door but that movement of the main door toward the auxiliary door mayoccur. Upon such occurrence the `hasp which .is carried by the main door will move in the :same direction as the main doorso that itwill begreleased from engagement with the inclined portion of the pin. When this release occurs thepin will d rop bythe action ofgravity until the space created bysuch movement is lled by a wider portionof the pin. The

' relationship between the pin, the hasp and the lockV bracket, illustrated in Fig-3 of .the drawing, is thereby again restored. .Movement vof the main door in opening .directionis thus .prohibitedrand this action Aoi? the lock will .continue until the main and auxiliary doors are fully closed. .Lashing of the main door and consequent wear upon the door Aand the lockparts are avoided.

By virtue of the instant inventionthe side edges of the pin are `straight and take-up of any clear ance created' by anyY movement .of the main door in closing direction .is obtained 'by means of the. inclination of the rear face of V.the pin. This construction eliminates the ,possibility of upward jumping of the pin when the car is subjected to impact since the stresses imposed upon the in'-Y clin'ed'face of the pin tendingto prevent jumping of the pin are in excess of those stresses tending to cause jumping .of the pin. .Danger of shearing of the sealingribbons is thereby avoided.

Y .It will be apparentthat numerous changes'and modiications in .the details olf-the invention will be clear to those skilled inthe art. It'is in` tended, therefore, that all such modifications and changes be comprehended within this invention,

'which is to be limited only by the scope of the claims appended hereto.
